Description
図1は、本実施形態のゴム部材の形成装置1(以下、単に「装置1」という場合がある)の模式的な側面図である。本実施形態の装置1は、ゴム押出機Tから押し出された押出ゴムGを、搬送方向下流側dにて切断してゴム部材(図示省略)に形成し得る。ゴム部材は、例えば、タイヤを構成するタイヤ構成用ゴム部材として利用される。図1には、押出ゴムGの搬送方向下流側dが矢印で示される。
2A 第1コンベヤ
2B 第2コンベヤ
6 貯留槽
G 押出ゴム

- 前記シュリンク工程は、前記貯留槽の底面から前記押出ゴムのU字状の最下部までの高さを調整する調整工程を含む請求項1乃至3のいずれかに記載のゴム部材の形成方法。
- ゴム押出機から連続的に押し出される押出ゴムを搬送する搬送手段と、搬送された前記押出ゴムを切断して所定長さのゴム部材を形成する切断手段と、搬送中に前記押出ゴムを収縮させるシュリンク手段とを具え、
前記搬送手段は、搬送方向上流側の第1コンベヤと、搬送方向下流側の第2コンベヤとを含み、
前記シュリンク手段は、前記第1コンベヤと第2コンベヤとの間に配されかつ0~25℃の温度の液体が貯められた貯留槽を有し、前記第1コンベヤからの前記押出ゴムが、前記液体中を拘束されずにU字状に弛んだ状態で通過することにより、前記押出ゴムを浮力を受けた状態で自由に収縮させたゴム部材の形成装置。
